Procedure
The same procedure was carried out as in Example (4a), except that 2-fluoro-4-hydroxy-5-methoxybenzaldehyde [CAS No. 79418-77-2] and t-butylchlorodimethylsilane were used instead of respectively the 3-hydroxy-5-methoxybenzaldehyde and chlorotriisopropylsilane, to give the title compound as a colorless oil.
